Email Sending Microsoft Outlook Outage

We are currently experiencing an issue affecting email deliveries to Microsoft-hosted addresses (including Outlook.com, Hotmail.com, Live.com, and Office 365). Messages sent to these domains may be delayed or deferred. A small portion of emails may still be delivered, but most are impacted.

This appears to be due to a service disruption on Microsoft’s side. Our systems are operating normally, and we are monitoring the situation closely.

Details for Outlook outage: https://status.cloud.microsoft/m365/

Microsoft has resolved the issue and we have confirmed that the service has back to normal.

Email Sending Yahoo Deferral

Yahoo has deferred the emails we send to them. This means emails to Yahoo & AOL addresses will be delayed or deferred.

More info on deferred emails can be found here:

We apologize for the inconvenience and are actively working to resolve this issue.

Email sending to Yahoo email addresses has returned back to normal.

We've re-routed Yahoo emails to our other mail servers. Yahoo might still defer a very small portion of the emails. But we'll keep monitoring this.
